Title: Sense circuit system
Inventor: KOUDA SHIGETO
IPC: G11C11/34
Filed: 1982-07-19
Abstract: PURPOSE:To prevent the malfunction due to the input of a noise electric charge generated on a bit/sense line, by adding a transistor (TR) for forming a potential barrier. CONSTITUTION:A voltage V1 is impressed to the gate electrode of an n-channel MOS TR 15 for forming a potential barrier. N-channel MOS TRs 16 and 17 for precharging precharge nodes 18 and 19 up to VCC-VT by a control signal phi having an amplitude VCC. A voltage V0 (<VCC) is impressed to the gate electrode of a TR 14 to precharge a bit/sense line 11 up to V0-VT. When the voltage V1 is so set that V0<V1<VCC is true, a channel surface potential V1-VT of the TR 15 is higher than the potential of nodes 18 and 19 and is lower than the potential of the bit/sense line 11. Even if a noise electric charge QN smaller than a signal electric charge QS is flowed to the sense circuit through the TR 14 from the bit/sense line 11, it is trapped by a potential well of the intermediate node 18 to have no influence upon the potential of the input node 19.

Title: Monitoring method for cell culture
Inventor: MITSUMORI FUMIHIKO
IPC: G01N15/02
Filed: 1986-05-28
Abstract: PURPOSE:To make exact measurement of the number of cells even in the case of having an intricate pattern and background by digitizing the cultured cell image taken into a device, processing the same by using a space filter and measuring the condition of the cultured cells. CONSTITUTION:The cell image in a culture vessel is inputted to an image processor by using a TV camera connected to a microscope. The taking-in of the cultured cell image is executed in the focal position where the distinct image having bright luminance in the central part of the cultured live cells and dark luminance in the peripheral part thereof is obtd. by deviating the focus from the state where the focus is thoroughly matched. The cultured cell image is taken in at the point of the time when the magnification inscribing the square shape of the space filter matrix of the size assigned by one cultured live cell is attained. The image is then binary coded by the suitable threshold value, and the picture element in the part where there is the live cell is made 1 and the picture element of the part where there is no live cell is made 0. The number of the live cells is calculated in accordance with (the number of the live cells = the number of the picture elements where there are the live cells/the number of the picture elements where one live cell exists). The exact measurement is made if the similar calculation is made with the number of the dead cells.

Abstract: PURPOSE:To extend the service life of a battery by dividing the case into a case when a low voltage alarm takes place at callout notice and a case when it takes place at reception, and suppressing the current consumption at callout notice between 1st and 2nd periods. CONSTITUTION:When a low voltage detection circuit 24 is operated at callout notice T1, a control circuit 23 controls a decoder 14 or various notice circuits and generates a notice signal once at that point of time.

Inventor: TANIMOTO SHIGEYA
IPC: H02K21/14
Filed: 1994-06-07
Abstract: PURPOSE:To suppress the drop of torque by making the inductance of a stator winding small. CONSTITUTION:Each permanent magnet 28 of a rotor 24 is made so that the cross section may be circular, and also each of these permanent magnets 28 is arranged at the iron core 26 of a rotor so that the side of a projection 28a may look toward the center of rotation of the rotor 24, and further a slit 30 extending in the radial direction is made at the section 26a positioned on the side of the recess 28b of the permanent magnet 28, of the iron core 26 of the rotor, in every pole. Though the section 26a is a section which becomes the magnetic path of a magnetic flux based on the current of a stator winding, the magnetic reductance of the magnetic path becomes large by forming a slit 30 here. Therefore, out of the magnetic fluxes based on the currents of the stator winding, the rate of flux through this section decreases, and the inductance of the stator winding becomes small.

A shield holding substrate 23 consisting of quartz glass which is separately prepared and which also has an antireflection film 22 formed is disposed upper and in contact with the BO lens 15. The joining process is carried out in a nitrogen atmosphere. The single layer film acts as an antireflection film when light beams passes from the air, and when the film is in contact with the holding substrate 23, it causes a kind of atomic joining. If the temp. is high in this process, the bonding strength is further increased.
